What are the different types of gear assemblies? Law of Gearing The common normal at the point of contact between a pair of teeth must always pass through the pitch point for all mating gear positions, according to the law of gearing. The design of the gear profile is based on this law. This is a must for the two gears to function properly. The angular velocity between two mating gears always remains constant. Therefore, from the Law of gearing we can derive the relationship as: where w is angular velocity of gear, n is the gear speed, d is the pitch diameter of the gear, T is number of teeth ..read more
